hey guys i just got my motor back from the shop that rebuilt it for me. the motor has been gone throught with all new forge piston, new head gasket, the head has been redone, and i just put in pte 580 injectors.the car has most aftermarket things done to it greedy timing belt, 250 walbo,new ngk wires, new plugs, the motor was running fine before with the same set up but then due to other problems i blow the head gasket and had the motor redone. so now i'm putting it and the car will just crank fast and nothing else. the car does have the maftpro on it,. as some of you all know me and my dad have alot of supras at the house and can swap most any part pretty easy.
things we have tested.
1.took cps out of the car lined everything up put it back in and didnt change anything.
2. too the cps out of a running car and lined everything up and didn't change anything.
3. changed coil packs didn't change anything.
4. changed ignitor didn't change anything.
5. unhook the 1st spark plug wire and test to see if it had spark and it does.
6. check all the grounds and fuses
i need help to get this motor running please let me know anything you all can think of. sorry if i missed spelled anything thanks

i put spark plugs in, i check the compression on number 1 and 6 and didn't get a reading, so i took the gauge and put it on another one of the cars and it worked fine so i retested the compression again and got nothing the niddle on the gauge doesn't move at all. not even a bump. and yeah i'm getting fuel. i can turn the crank and the cams moves so i'm not sure if it is in the timing belt. the motor was bored and had .020 over pistons put in. the shop that did the work is suppose to be very trust worthy they build 2jz and 7ms all the time not just a shadetree just to throw that in thanks guys

i would some what hate to say how much i spent i on the motor rebuild but this shop is suppose to be one of the best in a few states as far as toyota rebuilds. so i will say they had best to have put pistions rings on but i will be able to tell more tomorrow me and dad are going to test some timing options and then put some air to the piston to see where it goes if it is a ring or just a valve thin i will tell more tomorrow thanks for all your help so far
